Using this function we can create array of any data type, but if not data types is mentioned the default data type will be the "int" For e.g : from numpy import * Arr=array([10,20,30,40,50],int) is similar to arr = array([10,20,30,40,50]) While creating array if one of the values in the specified list belongs

In addition to basic types (integers, ﬂoats, etc.), the data type objects can also represent data structures. An item extracted from an array, e.g., by indexing, is represented by a Python object whose type is one of the array scalar types built in Numpy. The array scalars allow easy manipulation of also more complicated arrangements of data.

NumPy Fundamentals • Why Numpy? • Remember that Python does not limit lists to just elements of a single class • If we have a large list and we want to add a number to all of the elements, then Python will asks for each element: • What is the type of the element • Does the type support the + operation • Look up the code for the + and execute • This is slow

Jun 17, 2014 · The central feature of NumPy is the array object class. Arrays are similar to lists in Python, except that every element of an array must be of the same type, typically a numeric type like float or int. Arrays make operations with large amounts of numeric data very fast and are generally much more efficient than lists.
